MACHINE FOR THRESHING PEAS AND BEANS.

Specification of Letters Patent No. 29,315, dated July 24, 1860.

To all whom it 'may concern:

Be it known that I, JAMES T. SMITH, of Portsmouth, in the county of Norfolk and State of Virginia, have invented a new and Improved Machine for Threshing Peas and Beans; and I do hereby declare that the following is a full, clear, and exact description of t-he same, reference being had to the annexed drawings, making a part of this speciication, in which- Figure l is a side sectional view of an invention, taken in the line fr, Figs. 2 and 3. Fig. 2, an end view of the same. Fig. 3, a plan or top view of the same, with the hopper, beater-guard, and upper part of the fan-case removed. Figs. 4, 5 and 6 are detached views of the fan-case, beater-guard, and hopper.

Similar letters of reference indicate corresponding parts in the several figures.

' This invention has for its object the rapid threshing of peas and beans, and the separation of the pods and oifal therefrom at one operation, and with one and the same machine.

The invention consists in the employment or use of rotating beaters in connection with a stationary slotted plate and a fan arranged for joint operation, substantially as hereinafter shown to effect the desired end.

To enable those skilled in the art to fully understand and construct my invention I will proceed to describe it.

A represents a suitable frame in which a fan-case B, is fitted, and a box C; the fancase and box communicating with each other by a passage a, and the box having an inclined bottom provided with a screen 2),' below which bottom and screen there is an inclined bottom forming a chamber c, which is provided with a Hap or door d, at its outer end as shown clearly in Fig. l.

On the frame A, and directly over the box D, there is fitted transversely a shaft E, to which radial bars e, are attached, and to these bars e, metal plates F, are secured said plates extending the whole length of the bars and having parallel teeth or beaters f, projecting from them obliquely, as shown in Figs. 2 and 3.

On the frame A, there is secured transversely a metal plate G, which is slotted obliquely corresponding to the position of the beaters f, as shown clearly in Fig. 3. The slots g, in the plate G, are made somewhat wider than the beaters f, so that the latter may pass freely through the former. The spaces between the beaters f', may be about five-eighths of aninch, and they may project about three inches from the bars e.

The front edge of the plate G,-that is to say the bars it, formed by the slots g, are bent upward in a vertical position to form a fender, as shown at z', in Figs. l and 3.

On the frame A, and directly over the fan case B, there is placed a hopper H, which is simply a box provided with an inclined bottom which extends down to the plate G, as shown clearly in Fig. l.

I is a fan placed in the case B. The shaft of the fan projects through one end of the case, and has a pulley j, on it, around which and a pulley la, on one end of the shaft E, a belt Z, passes. On the opposite end of shaft E, there is placed a pinion m, into which a wheel n., gears, the shaft 0, of the wheel n, being the driving shaft.

The beaters f, are covered by a guard J, which is simply a hollow semi-cylinder.

The operation is as follows: The wheel n, is rotated by any convenient power, and the peas or beans to be threshed are fed into the hopper H, and they pass down within reach of the rotating beaters f, which, in passing through the slots g, of the plate G, thresh the peas or beans from the pods, the peas or beans and broken pods falling into the box O, the latter being expelled from the box, and at some distance from its mouth by the action of the blast generated by the fan I, while the peas or beans will be discharged, principally by their own gravity, and will drop directly down from the mouth of the box C, and thus be separated from the pods.

The chamber c, receives dust, and iine foreign substances which may be rather too heavy to be acted upon by the blast.

This machine has been practically tested and it operates well, threshing and fanning from 15 to 2O bushels of peas or beans per hour. By having the beaters f in an oblique position they operate more eficiently on the peas or beans, as the latter, in the pod, very frequently are presented to the beaters longitudinally with the machine, and the oblique position of the beaters insures a transverse or cross action of the latter on the pods; I do not however confine myself to the oblique position of the beaters.

Having thus described my nventon,what erate oonjontly as and for the purpose set I claim as new, and desire to secure by Letforth. ters Patent, is-

The rotating beaters f, and stationary 5 slotted plate G, combined with the fan I, Vtnesses:

and arranged in a suitable frame A, n rela- A. B. LooKrNs, tion With the hopper H, and box C, t0 op- SEYMOUR VILLIAMS.
